Title: Array type ultrasonic probe
Inventor: HARA YASUSHI
IPC: H04R17/00
Filed: 1989-12-08
Abstract: PURPOSE:To prevent the disturbance in the sound field of the ultrasonic waves to be transmitted and to obtain excellent frequency characteristics by packing materials having a high attenuation rate into the region of an element exposed part where a matching layer is not formed, thereby radiating the uniform ultrasonic waves from all the regions of the aperture radiating the ultrasonic waves of a probe. CONSTITUTION:A layer 8 formed by mixing microballoons and cork powder which are the materials having the high attenuation rate of frequencies is packed onto the earth part, i.e., a conductor 7. The ultrasonic wave radiated from the region of the earth electrode of a piezoelectric element 2 are attenuated by the layers 8 and the ultrasonic waves are no longer radiated to the outside or are extremely weak, even when radiated. No influence is thus exerted at all on the transmission and reception characteristics of this probe.

Title: Manufacturing of stimulated phosphorescent sheet
Inventor: NAKAMURA TAKASHI
IPC: G21K4/00
Filed: 1988-12-15
Abstract: PURPOSE:To improve a brightness of a stimulated phosphorescent body and to improve a sensitivity of a radiation image conversion panel by applying a heating treatment to a mixture of phosphorescent source materials or a heat processed one of the mixture under a high pressure to form a sintered body of a stimulated phosphorescent body and by slicing off the sintered body in a shape of a thin flake. CONSTITUTION:As phosphorescent source materials, a sort of rare earth compound selected from a group of Y2O3, La2O3 and Lu2O3, for example, a sort of a halogen donor selected from F, Cl, Br and I and a sort of cerium compound (a halogenated cerium and so on), are used. After being mixed, those phosphorescent source materials are heat-processed for several hours under around 300 to 600 deg.C. Then, an obtained heat-processed one is applied to a heating treatment under a high pressure condition. An atmosphere under which the heating treatment is applied, is a weak reducing atmosphere, a neutral one or a weak oxidation one. After being cooled down, a sintered body obtained by the treatment mentioned above, is taken out from a furnace and is sliced off in a shape of a thin flake. A thickness of the single flake is just a thickness itself of a stimulated phosphorescent sheet which forms a phosphorescent layer of a radiation image converter panel, that is to say, around 20mum to 1mm as an appropriate thickness.

Abstract: PURPOSE:To enhance the accuracy in length of a fuse, and to reduce the irregularity in fuse-blowing characteristics of the fuse by a method wherein the tip part of a cathode terminal is insulation-covered utilizing the accuracy of the cathode terminal which is assembled into a chain lead wire. CONSTITUTION:The entire circumference of the tip part of the cathode terminal 5 (bent in an L-shape), formed in the prescribed shape, is insulation-treated using the insulating resin and the like consisting of material such as thermosetting silicon resin, for example. Subsequently, a part of the cathode layer 1a of the element, welded to a cathode terminal 3, is also coated with the insulating resin such as thermosetting silicon resin and the like, and the non-insulating material of the cathode terminal is prevented from coming into contact with the cathode layer. Then, a fuse is connected to between the non-insulated part of the cathode terminal and the cathode layer 1a on the outer circumference of the element crossing the insulating material 5a located at the tip part of the cathode terminal 5, using a conductivity adhesive agent, soldering and the like. As said conductivity adhesive agent or the solder does not reach the insulating region when the above-mentioned connecting operation is conducted, the length the fuse is equalized with the length of the insulating part of the cathode electrode terminal.

Title: Motor control device for forklift
Inventor: KITAJIMA YASUHIKO
IPC: B60L7/12
Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To reduce the speed at a constant acceleration so as to maintain the constant braking distance in the case where an advance direction command from a forward and backward movement switching lever and the rotating direction of the motor are different from each other by controlling the acceleration at the predetermined acceleration. SOLUTION: When a forward and backward movement switching lever 14 is fallen to the forward movement position and an accel pedal 1 is operated, a torque command computing means 2 outputs the torque command 1T1 corresponding to the operated variable θ. In the case where the rotating directions coincide with each other, the torque command switching means 4 selects the torque command 1T1 *. Consequently, a motor 10 outputs the torque corresponding to the operated variable θ. Thereafter, when the lever 14 is switched to the backward movement position, since the advance direction command D* and the rotating direction ND of the motor are different from each other, the switching means 4 selects the torque command 2T2 *. As a result, acceleration of the motor 10 is controlled for deceleration on the basis of the acceleration command α* at the predetermined value.  Namely, even in the case where the movable load of a forklift and inclination of a road surface are changed, since the acceleration is controlled, speed is reduced at a constant acceleration.

Title: Musical tone control device
Inventor: SAKAMA MASAO
IPC: G10H1/34
Filed: 1990-11-24
Abstract: PURPOSE:To facilitate musical performance and to enable the prevention of wrong pitch indication by changing over a pitch group which one hand can indicate to a scale tone and a continuous semitone, on the bending state of the finger of the other hand. CONSTITUTION:A pitch group composed of five continuous pitches is determined by the bending state of the finger of one hand. One tone in the pitch group is selected through the bending state of the finger of the other hand. A selecting method for selecting the above tone by bending only any one of the five fingers is simplest, but other various selecting methods can be adopted. In addition to that, since a pitch group determining means has a changing over means, the pitch group can be switchedly composed of continuous scale tones or continuous semitones. In the case where the pitch group has been composed of the continuous semitones, semitone progress and a trill performance can be easily executed through the action of the finger of the other hand.

Title: Signal processing circuit for photometer
Inventor: MATSUYAMA EIICHI
IPC: H03F3/08
Filed: 1990-11-20
Abstract: PURPOSE:To improve the photometry precision by using one arithmetic amplifier, connecting two light receiving elements to each other with opposite polarities, and converting the difference between their photoelectric currents into a voltage by a diode. CONSTITUTION:Light receiving elements SPD1, SPD2 are connected to each other with opposite polarities. Diodes D1, D2 for converting photoelectric current into voltage are connected to each other with opposite polarities. Optical signals lambda1, lambda2 enter the respective elements SPD1, SPD2 and form photoelectric currents I1, I2. The difference current between the photoelectric currents I1, I2 is passed through the diode D1 or D2 and converted into a voltage.m The output voltage V0 of an arithmetic amplifier A1 is reduced as an error by this portion as the offset voltage value of the amplifier A1 is reduced. Thus, the photometry precision can be improved.

Filed: 1995-11-14
Abstract: PROBLEM TO BE SOLVED: To generate clock signals with varied phases stably by providing a 1st clock generator and a 2nd clock generator generating inverted clock signals and delaying outputs of them. SOLUTION: A clock signal received from a clock input terminal 1 is fed to a counter 5 noninvertingly via a buffer 3 and inverted by a buffer 4 as a clock with a phase shift by 180 deg., and the inverted clock signal is fed to a counter 6. The counter 5 provides an output of a higher order bit (MSB) in two bits. For example, 2 bits in a binary system are '00', '01', '10', '11' (cyclic codes), then the MSB denotes 0, 0, 1, 1. Then an output of 1/4 frequency division of the received clock is obtained. The counter 6 provides an output of a 2nd smaller bit in 3-bit signals (2nd bit from the LSB). Then the buffer 3 and the buffer 5 with inverter generate noninverting and inverting clock signals respectively, each clock is delayed at a D FF by, e.g. 45 deg. each to obtain constant phase clock signals equal to a horizontal synchronizing signal.
